    - Sending a WM_ message from WDM to app Hi all! How can I send a windows message to an application from a WDM driver? Several years ago I wrote a VxD driver for an ISA device used in our equipment. Through an IOCTL message, our application would pass its handle and the VxD would store it. When the VxD had something ready for us it would use the handle to send the app a windows message at which time we might have to do some sort of IOCTL to the driver or more commonly read a message in dualported memory. Good or bad programming practice it worked quite well. We are migrating to XPe and I'm trying to translate this possibly dubious practice from VxD to WDM. I have all the tools. XP DDK, Walter Oneys book and Compuware Driverworks. I used VtoolsD for the last driver.

    - how to deal with packet in calling NdisMIndicateReceivePacket I am trying to write a virtual network drive which the incoming traffic is from DeviceIoControl routines instead of a "real" NIC. Whenever the driver get any incoming traffic, it should call NdisMIndicateReceivePacket() to notify the protocol driver that a packet is ready. However, one of the input is (PPNDIS_PACKET) ReceivePackets. It turns out that there should be an array of packets. Here are my questions: 1) How often should I call NdisMIndicateReceivePacket()? 2) How should I deal with the packet array allocation? Should I allocate packet and associated buffer space in initialization? or whenever I need? Thanks!! Tag: bulkusb, isousb, selsusp Tag: 37252

    - IoQueueWorkItem on Win98 ?!?!? Hi, I'm used to use the same P&P driver on Win2k\Win XP, and Win98. After adding the "IoQueueWorkItem" routine, the driver cant be loaded on Win98. I read somewhere that it doesn't supported on Win98. Is it true ? Is there any new/better routine that i can use for all WDM OS's ? I'm trying to avoid re-compiling the driver for each OS. Thanks a lot mich Tag: bulkusb, isousb, selsusp Tag: 37246

    - Virtual Printer Driver Hi, I have to develop a virtual printer driver which can do the following stuff: - generating a bitmap( color/monochrome) - generation a textfile, in which all DrvTextOut string are stored - the complete strings should be parsed and replaced, if needed( special sequences ) - the replaced string should be updated in the bitmap I have tested both the msplotter sample in which I can easily acess the text in DrvTextOut and the oemdll sample in with which I can generate a bitmap. But the parsing and manipulation of matched string in the bitmap makes me headaches. Can a unidriver plugin do all the things? Any hints, tips are welcome.

    - SetupDiGetDeviceRegistryProperty The MSDN online suggests in "Driver Information in the Registry" http://msdn.microsoft.com/library/default.asp? url=/library/en-us/install/hh/install/install-over_6e3r.asp That IoGetDeviceProperty() and SetupDiGetDeviceRegistryProperty() be used instead of accessing the registry directly. I'm interested in getting the resources used by drivers. I realize that Device Manager reports these resources and so they are available. I tried using IoGetDeviceProperty, but blue screens with PNP_DETECTED_FATAL_ERROR 0x02 got in my way, thus I'm looking at SetupDiGetDeviceRegistryProperty(). However, the DevicePropertyBootConfigurationTranslated is not apparently available from SetupDiGetDeviceRegistryProperty (). The SPDRP_DEVICE_POWER_DATA doesn't provide the resources, and I'm looking at SPDRP_DRIVER which provides the Driver Key in the registry (Software Key). It also refers back to "Driver Information in the Registry." Can I get the resources for drivers without looking in the registry? Do I have to read the ...\Control\AllocConfig which is a REG_RESOURCE_LIST? And if so, what is the format of that binary data, a CM_RESOURCE_LIST type of thing?

    - Audio Midi Driver Hello, This is an audio/midi driver related problem. I hope somebody can help. I try to write a simple midi-in driver where data is transfered from a device to some midi software application. Therefore i took the DDK dmusUART sample as a basis and modified it to my needs. Now the driver is just for input. By orienting at the sample and the DDK documentation all pin declarations and property request handlers should be correct. The device shows up correctly in the audio device listings and can be selected as input. But when i try to connect the IMXF is created, initialized and the output connects and immediately disconnects. After that the IMFX is destroyed. This happens about 28 times and no data is transfered. After that the application beliefs it ist connected but the driver shows no singns of life anymore and does not react on any further connection attempts. Can anyone help? Thanks. Best regards, Timo Tag: bulkusb, isousb, selsusp Tag: 37237

What commands does *PrintableArea, *PrintableOrigin and *CursorOrigin insert into the PCL stream ? What is this used for ? I could not find much documentation about this in the DDK help also. 2. The printable area length according to calculation should have been 12760 (13200 - 220 - 220), but here it is only 12720 , where did the 40 units go? I have seen this difference in other In-box GPD's 3.I had created a GPD for my printer, letter paper size portrait mode values are as follows, *PrintableArea:PAIR(9800, 12800) *PrintableOrigin: PAIR(200, 200) *CursorOrigin: PAIR(200, 200) *Command: CmdSelect { *Order: DOC_SETUP.21 *Cmd: "<1B>&l2a8c1E" } When tested with WHQL tool the rectangle did not have the right side. When I changed the *PrintableArea to *PrintableArea:PAIR(9799, 12800) it started working fine. These measures are in terms of 1/1200 of an inch, how did that 1 unit make the difference ? -Thanks in advance Tag: bulkusb, isousb, selsusp Tag: 37236

    - FW: Only dmDuplex member(PS Driver) cannot be updated on reason of PROPSHEETUI_REASON_DESTROY ***FW from microsoft.public.ddk.win2000.printer.video Hi All I am developing a PostScript printer driver by modifying WindowsXP ddk samples "Windows 2000 OEM UI Customization Sample (PS)", and encounterring a problem on updating dmDuplex member of public DEVMODE. It's very weird: 1. On original sample, system standard "Layout" and "Color" sheet is hidden, if I don't hide the 2 sheets(directly return E_NOTIMPL in IOemUI2::HideStandardUI()), then dmDuplex can be updated normally. 2. The problem is not reproduced on updating other public DEVMODE members, such as dmOrientation, dmCopies, dmPaperSize and dmScale. I was not using CPSUI to make my plugin property sheets, so I cannot use DrvUpdateUISetting() to update user settings. Below is the testing code I am using to update public and private DEVMODE under reason of PROPSHEETUI_REASON_DESTROY on hrOEMDocumentPropertySheets(PPROPSHEETUI_INFO pPSUIInfo, ...): ... POEMUIPSPARAM pOEMUIParam; PDEVMODE pTestDevmode; pOEMUIParam = (POEMUIPSPARAM)pPSUIInfo->lParamInit; pTestDevmode = (PDEVMODE) pOEMUIParam->pPublicDM; //check value of pTestDevmode->dmDuplex at here: it is 1. pTestDevmode->dmDuplex = 2; pPSUIInfo->pfnComPropSheet(pPSUIInfo->hComPropSheet, CPSFUNC_SET_RESULT, (LPARAM)NULL, (LPARAM)CPSUI_OK); //check value of pTestDevmode->dmDuplex at here: // it is 1 if Layout and Color sheet is hidden. <-- Problem! // it is 2 if Layout and Color sheet is not hidden. <-- Expected ... I will be appreciated if anyone can give me any advice on this. Tag: bulkusb, isousb, selsusp Tag: 37231

    - Using KeSetTimerEx Hello All, Basically my requirement is to perform some action after every fixed time interval. I therefore create a "synchronization" type timer and using KeSetTimerEx () i schedule the timer. But it looks like the timer is not called at the time interval i need it to invoke the timer callback routine. I check this using KeQuerySystemTime (). Following are the steps: 1) KeInitializeTimerEx (&(pDevExt->myTimer), SynchronizationTimer); KeInitializeDpc (&(pDevExt->myTimerDpc), myTimerRoutine, pKsDev); 2) timerDelay.QuadPart = -180000; // 18 ms KeSetTimerEx (&(pDevExt->myTimer), timerDelay, 18, &(pDevExt->myTimerDpc)); But what i observed to my dismay is that my myTimerRoutine () was called at approximate intervals like: 15.625 ms 15.625 ms 15.625 ms 15.625 ms 31.250 ms and so on as the pattern keeps repeating.... Any reason why this is happenning? Is it possible to make the timer routine be called at the exact timer interval? Also, i used KeSetTimerEx (&(pDevExt->myTimer), timerDelay, &(pDevExt->myTimerDpc)); but the timer routine got invoked only once! Is there something iam missing here? Can someone throw some light on this? Regards, Hari. Tag: bulkusb, isousb, selsusp Tag: 37230

    - Help required on Surprise Removal in XP (NDIS5.1) when writing NDIS-WDM Hello, I am writing a NDIS-WDM (USB ) driver for NDIS5.1 (XP). I used the sample from Eliyas. I saw the mailing lists and set the NDIS_ATTRIBUTE_SURPRISE_REMOVAL_OK bit in the call to NdisMSetAttributesEx from MiniportInitialize function. And I implemented the additional MiniportPnPEventNotify function also. When I plug-in the cable, Windows loads my driver. But the "System Tray" icon for "Safely Remove Hardware" appears. When I remove the cable, I get a call to my PnPEventNotify function with SurpriseRemoved event set. There is no pop-up error message as per XP standards. But, I was under the understanding that if the SURPRISE_REMOVAL_OK bit is set, even the "tray icon" does not appear. Please help me in making sure that my understanding is right. If I am wrong, what have I done wrong in the driver that this is not working? Any pointers or any kind of help is greatly appreciated. Thanks in advance for the great help.

    - Did anybody try to write printer drivers for 10 or 12-bit gray level printers? Hi, The majority of printer drivers under Windows support only 8-bit B/W printers or 8-bit per channel color printers. Has anybody every tried to write a printer driver to support 10-bit (or higher) gray level printers under MS Windows environments? Specifically, if I have a 10-bit gray level image and a printer that does support 10-bit printing, I would like the full 10 bits of every pixel go un-truncated all the way from the application to the printing engine. If anybody did this before, could you please share your experiences? How would the 10-bit requirement fits the overall Windows printing architecture? Thanks a lot.

    - IRP FilterResourceReq. and mf.sys not working The problem I am seeing is that my driver successfully requests new PCI memory in the Filter Resource IRP when installed directly but fails when installed through MIcorsofts multifunction mf.sys. I need to allocate an additional PCI Memory Region for a driver to fix a HW config problem. Support Win2000 and later, testing on Win XP. In the IRP_MN_FILTER_RESOURCE_REQUIREMENTS, I allocate memory for a new IO_RESOURCE_REQUIREMENTS_LIST, copy the existing list to the new one, append the new memory region to the end, update count and size, clear and free existing list, link the new one into the IRP, and pass the IRP down. When I install this driver directly for the PCI Vendor/Device ID it works. In the Start Device IRP I see the original resources plus the new resource that I have allocated. After installing, in the Driver Properties Resource Tab, I see the original resources plus the new resource. Driver works fine. The problem comes when I use multifunction mf.sys to enumerate the functions and install the exact same driver in the enumerated function. My .inf installs mf.sys for the PCI Device and Vendor ID and currently enumerates one function. When the driver is installed for that function, I see the Filter Resource IRP but never receive the Start Device IRP. The driver fails to start and indicates it can not find enough free resources and to restart. Restarting does not help still gives same error. Any thoughts or ideas on what could be going wrong? Why does mf.sys effect allocating new resources? I did notice that the resource list is not the same between the two cases. The actual memory and IRQ regions are identical but the standalone driver has some Private Data (Type 0x81) entries as well. Thanks, Stefan L Tag: bulkusb, isousb, selsusp Tag: 37167

    - Can NDIS5 drivers be "chained" in Windows XP? Several years ago we developed an NDIS2 driver in OS/2. When our code is notified a frame is available (typically via ReceiveLookahead indication), it returns SUCCESS to indicate it will accept and copy the frame. If there is more than one driver in the chain, the next driver does NOT get the indication. Our code also returns FORWARD_FRAME when it wishes to pass along a frame to the next driver instance in its chain without accepting it and it returns FRAME_REJECTED when it does not want to accept the frame but also does not want to pass it to the next driver in the chain. The ability to chain together drivers and have those toward the rear of the chain NOT see frames consumed by those toward the front can be an important performance boost in some situations for us. We've recently had an outside company rewrite our driver for NDIS in Windows XP. This driver does not support the idea of a chain of instances where an instance that receives a frame can choose to accept or reject the frame such that any other instances of the driver do not receive the frame at all. The outside vendor cannot determine if/how this can be done in Windows. Is there a way to achieve this behavior in Windows XP? Thanks, Stephen Tag: bulkusb, isousb, selsusp Tag: 37164

The printable area length according to calculation should have been 12760 (13200 - 220 - 220), but here it is only 12720 , where did the 40 units go? 3.I had created a GPD for my printer, letter paper size portrait mode values are as follows, *PrintableArea:PAIR(9800, 12800) *PrintableOrigin: PAIR(200, 200) *CursorOrigin: PAIR(200, 200) *Command: CmdSelect { *Order: DOC_SETUP.21 *Cmd: "<1B>&l2a8c1e-50U" } When tested with WHQL tool the rectangle did not have the right side. When I changed the *PrintableArea to *PrintableArea:PAIR(9799, 12800) it started working fine. These measures are in terms of 1/1200 of an inch, how did that 1 unit make the difference ? Note:I have "-50U" as part of the command to left offset the margin by 50 units i.e. my printers left margin starts at 1/6 of an inch, since the default left margin in PCL is 1/4 of an inch I am adding this left offset command.

    - Accessing PCI Configuration Space I want to know the various other methods of how we can access the PCI Configuration space from our driver. One is the Standrd way of using CM_RESOURCE_LIST structure which is what i am following now, another i know is by accessing the CF8 and CFC register. Please tell me the other Methods for reading the configuration space and retrieving the information from there. Thank You All Tag: bulkusb, isousb, selsusp Tag: 37157

    - Cubas SX V1.0 hangs on MIDI initialisation Problem: Cubas SX V1.0 hangs 15 seconds on the MIDI initialisation if our AV Stream driver exports a MIDI Pin for rendering. Detail: The process services.exe uses 100% CPU time during initialisation. The Midi Pin works well with other applications and it works also with Cubase. OS: Windows XP, SP1 DirectX: 8.1 PIN Properties: MajorFormat = KSDATAFORMAT_TYPE_MUSIC; SubFormat = STATIC_KSDATAFORMAT_SUBTYPE_MIDI; Specifier = KSDATAFORMAT_SPECIFIER_NONE; Technology = KSMUSIC_TECHNOLOGY_PORT; The pin does not implement DMUSIC or any other properties. Is it required or recommented to implement additional formats or properties? I'm not sure if this is caused by Cubase, Windows or our driver. Can you give me a hint to solve this?

    - Resources Problem (2) (First Question in the bottom)... Hope yopu can help me! Hi!!! I checked and it seems ok. So I will tell you what happens in my debugging: I created a simple driver(withot any I/O, memory or IRQ), which I can install to a non- existent hardware. The run goes like: PCIETH - Version 1.00.000 Dec 8 2003 15:17:25 PCIETH - Entering AddDevice: DriverObject 85DEDA70, pdo 857EA690 PCIETH - PNP Request (IRP_MN_FILTER_RESOURCE_REQUIREMENTS) PCIETH - PNP Request (IRP_MN_START_DEVICE) PCIETH - To WORKING from STOPPED PCIETH - PNP Request (IRP_MN_QUERY_CAPABILITIES) PCIETH - PNP Request (IRP_MN_QUERY_PNP_DEVICE_STATE) PCIETH - PNP Request (IRP_MN_QUERY_DEVICE_RELATIONS) And the it's ok, I can communicate with this driver, but when I install the same one to my chip it stops after the PNP minor function resource requirements (supposedly managed by the PCI bus): PCIETH - Version 1.00.000 Dec 8 2003 15:17:25 PCIETH - Entering AddDevice: DriverObject 85DEDA70, pdo 857EA690 PCIETH - PNP Request (IRP_MN_FILTER_RESOURCE_REQUIREMENTS) PCIETH - PNP Request (IRP_MN_QUERY_STOP_DEVICE) PCIETH - PNP Request (IRP_MN_QUERY_STOP_DEVICE) PCIETH - PNP Request (IRP_MN_CANCEL_STOP_DEVICE) So obviosly as you say it will never work... So I re-start the computer as asked by windows and the it marks this resource overlaping in the I/O area with an intel pentium ii xeon processor to agp controller, but the device manager gives me this info: Intel I/O area: 03B0-03BB and 03CO-03DF My chip: F000-FFFF Now, do you now how can I fix this?

    - Forcing DMA bounce buffers upon MapTransfer Greetings all, I'm curious if there is any method to force a scatter-gather DMA list to utilize bounce buffers when calling MapTransfer. By "bounce buffer", I refer to the intermediate buffer that has to be flushed/copied for pages that are outside the device's addressable range. That is, the reason FlushAdapterBuffers is expected after performing the DMA. In my case, I have a 32-bit PCI device that I am preparing for AMD-64 operation. I can't load up my motherboard with >4 GB to try this, though, so I was hoping to fake it with a secret registry key or something. I'm pretty sure my code will work, but I would like to see what kind of impact the copying times will have on the device data throughput. All thoughts appreciated! -E.

    - Floppy Disk IOCTL functions? Hi, I want to make a floppy disk format utility for windows XP. This format utility will only be formatting A:\ or B:\ floppy disk drives. I will want to put a unknown disk format on the disk and it uses 256 byte/sectors. I see the Microsoft example in the DDK for the floppy disk driver, but if it's possible to do this without making a driver in Windows XP I'd sure like to know. If anyone can help?

    - Does USBCAMD support USB Bulk Mode? Hello: I am working on a USBCAMD2 mini-driver; the hardware for this driver uses USB bulk mode to transfer data. Does USBCAMD2 support bulk mode? It seems like BULK mode support was added but not fully debugged (example: on application exit, a spin lock is acquired, then acquired again causing problems later).

Hi All,

There is the Pending I/O queue called NewRequestsQueue,

and a procedure QueueRequest intended to enqueue requests while the Pending
I/O queue is in HoldRequests state, and a procedure ProcessQueuedRequests
intended to deplete the queue.

The ProcessQueuedRequests is called in appropriate places, but the
QueueRequest is never called, why?

TIA

Andrew
